摘要
为计算斜交的平行式墩台布置桥梁设计中直线与缓和曲线交点桩号,采用牛顿迭代法进行求解.该方法具有趋近次数少、精度满足要求的特点.经实际论证,该方法为近似求解弯斜坡桥直线与缓和曲线交点桩号较好的方法之一.
Skew bridge pier and abutment adopt parallel＇s axis layout,in order to describe the easement curve and straight line intersection point＇s mileage.This paper describes Newton-Raphson method to solve this problem,approaching number of times is not too much,and the required precision is very good.The results show that its one of good methods to describe the easement curve and straight line intersection point＇s mileage of the skew curved and ramp bridge.
